spheroidal

In petrography, noting the cracking or parting of rocks upon shrinking, commonly from cooling, whereby they break into spheroidal masses. It is the same phenomenon as perlitic cracking in volcanic glasses. The term is sometimes used as a synonym of orbicular as applied to certain granites and diorites.

Having the form of a spheroid.

the state of a liquid, as water, when, on being thrown on a surface of highly heated metal, it rolls about in spheroidal drops or masses, at a temperature several degrees below ebullition, and without actual contact with the heated surface, — a phenomenon due to the repulsive force of heat, the intervention of a cushion of nonconducting vapor, and the cooling effect of evaporation.

Like a spheroid. Roughly spherical, approximately round, roughly ball shaped.
